Figure 2. GABA depolarizes GCPs.
(A) GABA-induced currents recorded at different holding potentials ranging from −60 to +10 mV (marked to the left of the perforated patch-clamp records). (B) Current-voltage curve of GABA-induced currents for the traces shown in (B). (C) A representative current clamp record of a GCP depolarized by exogenous GABA application (100 μM, 2 s at arrow) in the EGL. Gramicidin perforated patch clamp was used. (D) DIC photograph of a patched cerebellar GCP in the EGL.
